Great app. Whatever they updated just within this week has messed up the app where it doesn’t sit right on the screen. The very top of the app appears at the bottom of your the phone screen. It reminds me of a film slide when you had the film moved up to much and see the top of the film at the bottom of the picture. Makes it hard to select those options that are in the corner of the top of the screen. Please fix it soon. Beside this, I would have a five star rating by me. I’m also giving it a low rating because when you go to the developers website, there is no place to leave any contact information or to tell them any problems being experienced.

Only app that meets my specific need

I use the touch controls on this app to help memorize material. It’s the only app I’m aware of which lets me touch the screen to pause/resume, swipe to skip/rewind, and even touch to speed up/slow down. I can do all of this without looking at the phone. The only downside is that the latest update seemed to break the ability to play files on Dropbox. I have a workaround where I can find the app in Dropbox and then export to SpeedUp so it’s not a showstopper for me.

Best audiobook player I’ve tried!

I’ve been using this app for 8 years, it’s the best audiobook player you can get on the market. It has unique ability to repeat playing a book after the end. You can’t find this feature in any other audiobook player. The settings also have many useful features for both music & audiobook. Will buy again (if next version available)
